Edinburgh-based Skyscanner said Fogg will be integrated into its search site by the end of the year, and will expand from currently being available in English and Spanish to being available in 30 languages to cover Skyscanner's global search markets.

Skyscanner said all five of Fogg's staff will be based in a new Skyscanner office in Barcelona, and the company said it also plans to add additional staff at the new office as a result of the deal, though no number was given.

The search company, which had until recently primarily focussed on flight search services, has now expanded its offering to car rental search services across 200 global markets.

Skyscanner described the Fogg acquisition as “a significant step in Skyscanner’s strategy of expanding its travel offering into other important areas of its users’ travel plans”.

Chief executive Gareth Williams said: “Our users are going to love hotel search as a result of this acquisition.

“We built the best flight search product anywhere in the world.

“We then expanded that offering into car rental. And today we've taken a big step towards completing the picture in the space of hotel search.”

Carlos González, chief executive of Fogg, added: “This is an exciting time for our small team.

“After four years of building the fastest, most human hotel search engine, we’re finally able to accelerate our ambitions by joining the world’s fastest growing international travel search company.”

Skyscanner, Europe's most visited online travel search engine, said this latest acquisition comes at a time when it is also moving rapidly into the Americas, including the US, Canada and Latin American markets.

The company recently opened a Miami hub office for the Americas region.

Skyscanner also agreed a partnership with China's largest search engine, Baidu, last year to power its international flight search, which also saw Skyscanner open a new office in Beijing.
